Tesla reveals a sleek solar panel built for your existing roof

Tesla's home energy efforts might be centered around its solar roofs, but it knows that not everyone can (or wants to) rip up their roof just to bring renewable energy to their home. To that end, the company is offering a first glimpse at Panasonic-made solar panels that would go on top of your existing roof. Unlike many aftermarket options, this would be relatively slick and unintrusive -- the panels have "integrated front skirts and no visible mounting hardware." While it'll be patently obvious that you have solar energy on your roof, it shouldn't be the eyesore you sometimes get with conventional designs.

Boston, Apr 14 (PTI) In a breakthrough, scientists have developed a new system that can harvest litres of water from the air everyday using just ambient sunlight, even in dry or desert climates. The solar - powered harvester , which can work in conditions as low as 20 per cent humidity

A tiny box produces fresh water using only sunlight for power . Could it help solve our global water crisis?

A small, solar-powered device that pulls fresh water from the air? Scientists at MIT and UC Berkeley have created a prototype that does just that -- and it only requires 20-30 percent humidity to work.

Professor Omar Yaghi, one of the senior scientists on the project, is calling the harvester "personalized water." He envisions a future where water is supplied "off-grid, where you have a device at home running on ambient solar for delivering water that satisfies the needs of a household," Yaghi said in a release.

Yaghi, a UC Berkeley chemistry professor, is also the inventor of the key element of the water harvester -- metal-organic frameworks, or MOF. MOFs are compounds created by combining metals with organic molecules. The resulting materials can be highly absorbent, making them ideal for storing liquids and gas. There are now some 20,000 different MOFs created by researchers and scientists with different properties and applications.

This device claims to turn any surface into a smart interface

Welle can instantly turn any surface into a smart interface, according to CEO and founder Mark Zeng. The smart-home controlling device uses sonar technology to read hand gestures on any surface.The company's Kickstarter campaign was launched in late March, and in just 21 hours, it hit the funding goal of &dollar;20,000. As of April 10, there are over 500 Kickstarter backers for the device.Welle was created with a specific gap in the smart technology market in mind."There is a limited interactive surface of our current technology. Welle was created to solve this problem.

In this case, Yaghi and his team at Berkeley created a MOF that binds to water. He then approached mechanical engineer Evelyn Wang of MIT about using the MOF to create a water-collecting device.

This, in addition to its ability to operate in low humidity conditions (generally below 40 percent humidity is considered dry air), means the harvester could represent a huge breakthrough for bringing water to places that desperately need it. Both Yaghi and Wang believe they've barely tapped the concept's potential. For example, the current MOF can absorb 20 percent of its weight in water. Future MOFs might be able to absorb 40 percent or more.

Giant Water Plume Detected Again on Jupiter Moon Europa

What appears to be a huge plume of water vapor has again been spotted emanating from Jupiter's icy moon Europa.NASA's Hubble Space Telescope detected a 62-mile-high (100 kilometers) candidate plume near Europa's equator in February 2016, researchers and agency officials announced today (April 13).

A tiny box produces fresh water using only sunlight for power . Could it help solve our global water crisis?

In a breakthrough, scientists have developed a new system that can harvest liters of water from the air every day using just ambient sunlight, even in dry or desert climates. The solar - powered harvester , which can work in conditions as low as 20 percent humidity

Freshwater scarcity is a global problem of immense proportions. Recent estimates show 4 billion people -- that's two-thirds of the world's population -- experience acute water scarcity at least one month of the year. Half a billion people don't have enough water all year round.

This crisis extends far beyond the developing world. California's historically severe drought has finally just ended, but the state typically experiences big fluctuations in rainfall from year to year. Climate change could make those swings even more extreme (check out this cool Gizmodo gallery showing differences between California in drought and California today).

Maybe in the not-too-distant future, we'll all have one of these devices to tide us over till the rains come again.

3 Google Pixel 2 Devices Coming In 2017? .
The existence of a third Pixel device was first indicated by some reports in March.It seems that the company might cash in on that success by launching three devices in the Pixel series this year. The company has been launching two flagship smartphones for the past couple of years, just like rivals Apple and Samsung, both of which launch a large and a regular size flagship device every year.
